AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
1222 PM EST WED DEC 5 2012

.SYNOPSIS...
ISSUED AT 332 AM EST WED DEC 5 2012
HIGH PRESSURE OVER MICHIGAN WILL MEAN PARTLY CLOUDY SKIES TODAY.
HIGH TEMPERATURES IN THE MID TO UPPER 30S WILL SLOWLY RISE TO THE
LOWER 40S THURSDAY AS THE HIGH SLIPS EAST AND WARMER AIR RETURNS TO
THE AREA. MIXED RAIN AND SNOW ARE POSSIBLE OVER THE WEEKEND AS A
STORM SYSTEM MOVES NORTHEAST TOWARD THE GREAT LAKES.

&&

.UPDATE...
ISSUED AT 1045 AM EST WED DEC 5 2012

WINDS HAVE COME AROUND TO MORE NORTHERLY AND WILL CONTINUE TO
SHIFT TO THE EAST/NORTHEAST OVER THE NEXT COUPLE OF HOURS. AS A
RESULT...THE WINDS AND WAVES ARE NO LONGER POSING A THREAT TO
SMALL CRAFT SO UPDATED TO CANCEL THE SMALL CRAFT ADVISORY FOR THIS
AFTERNOON. WINDS WILL BE ON THE INCREASE LATE TONIGHT FROM THE
SOUTHWEST...SO LIKELY SMALL CRAFT ADVISORY FOR TONIGHT AND
THURSDAY...BUT WILL EVALUATE THIS AFTERNOON FOR SPECIFICS ON
TIMING THE THREAT.

OTHERWISE...REMAINDER OF THE FORECAST ON TRACK THIS MORNING.

&&

.SHORT TERM...(TODAY THROUGH FRIDAY)
ISSUED AT 332 AM EST WED DEC 5 2012

FORECAST CONCERNS DEAL WITH PCPN TRENDS THURSDAY NIGHT AND FRIDAY.

THE CORE OF THE COLD AIR MOVING OVER LOWER MICHIGAN AND CAUSING SOME
STRATOCU WILL DRIFT EAST TODAY LEADING TO PT CLDY SKIES. THE NEXT
WEATHER SYSTEM WILL BE THE APPROACH OF BOTH A COLD FRONT AND A WAVE
OF LOW PRESSURE THURSDAY NIGHT. ISENTROPIC LIFT NEAR THE FRONTAL
BOUNDARY LEADS TO LOW CONDENSATION PRESSURE DEFICITS AND RAIN
THURSDAY NIGHT ACROSS THE CWA. APPROACHING LOW PRESSURE FROM THE SRN
PLAINS WILL ALSO DRAW SOME MOISTURE NWD. AS THE WAVES MOVES BY
FRIDAY...SOME COLDER AIR WILL WORK INTO THE SYSTEM RESULTING IN
MIXED RAIN AND SNOW OVER THE NRN CWA.

.LONG TERM...(FRIDAY NIGHT THROUGH TUESDAY)
ISSUED AT 332 AM EST WED DEC 5 2012

WE WILL MAINTAIN LOW POPS FOR SOME MIXED LIGHT RAIN AND LIGHT SNOW
SHOWERS FRIDAY NIGHT THROUGH SATURDAY. THIS WITH A NEARLY STATIONARY
BOUNDARY DRAPED ACROSS THE LWR OH VALLEY REGION AND SOME LIGHT
OVERRUNNING PCPN EXPECTED WELL TO THE NORTH OF THAT BOUNDARY INTO
SOUTHERN LWR MI.

THE FCST FOR LATE IN THE WEEKEND INTO EARLY NEXT WEEK IS COMPLICATED
DUE TO MEDIUM RANGE GUIDANCE DISCREPANCIES AND LACK OF RUN TO RUN
CONSISTENCY. WE WILL LEAN TOWARD THE 00Z ECMWF WHICH SUGGESTS THAT
THE BOUNDARY WILL LIFT NORTHWARD WITH A LOW PRESSURE WAVE SUNDAY
CAUSING PCPN TO CHANGE TO MAINLY PLAIN RAIN SHOWERS.

THE UPPER LEVEL PATTERN WILL BECOME MORE AMPLIFIED SUNDAY INTO EARLY
NEXT WEEK AS AN UPPER LEVEL TROUGH DEEPENS OVER THE PLAINS STATES
AND SHIFTS EAST INTO OUR REGION TOWARD TUESDAY. THIS PATTERN COULD
BE CONDUCIVE TO CYCLOGENESIS OVER THE ARKLATEX REGION SATURDAY
NIGHT/SUNDAY AND THAT LOW PRESSURE SYSTEM WILL TRACK NORTHEASTWARD.

00Z GFS GUIDANCE SUGGESTS THIS SYSTEM COULD BRING SOME ACCUMULATING
SNOW INTO PORTIONS OF LWR MI AS EARLY AS LATE SUNDAY AND MAINLY FOR
MONDAY AND TUESDAY. HOWEVER IT IS NOTED THAT THE 00Z ECMWF ONLY
SHOWS A FAIRLY WEAK LOW TRACKING NE THRU OUR REGION SUNDAY NIGHT
(MUCH FASTER THAN THE 12Z EC) AND DOES NOT SHOW NEARLY AS MUCH
POTENTIAL FOR ACCUMULATING SNOW EARLY NEXT WEEK.

TEMPS WILL AVERAGE A LITTLE ABOVE NORMAL FRIDAY NIGHT THROUGH SUNDAY
BEFORE RETURNING TO NEAR TO EVEN POTENTIALLY A LITTLE BELOW NORMAL
FOR EARLY NEXT WEEK.

&&

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z THURSDAY AFTERNOON)
ISSUED AT 1222 PM EST WED DEC 5 2012

AN AREA OF STRATOCU WITH CEILINGS OF 2500 TO 3000 FT EXTENDED OVER
CENTRAL LOWER MICHIGAN NORTHEAST OF A LAN TO LDM LINE. TRENDS SHOW
THESE CLOUDS WERE ERODING AS A DRIER NE FLOW TAKES OVER. THEREFORE
HAVE GONE OPTIMISTIC WITH THE TAFS AND KEPT ALL SITES VFR THROUGH
THE NEXT 24 HOUR.

ONLY SIGNIFICANT AVIATION CHANGE WILL BE INCREASING SSE WINDS
OVERNIGHT ALONG THE COAST AND THESE MODERATE WINDS WILL MOVE
INLAND THURSDAY MORNING.

&&

.MARINE...
ISSUED AT 1045 AM EST WED DEC 5 2012

WINDS AND WAVES NO LONGER EXPECTED TO POSE A THREAT TO SMALL CRAFT
THIS AFTERNOON AND HAVE CANCELLED THE SMALL CRAFT ADVISORY IN
EFFECT FOR TODAY. WINDS WILL SHIFT TO THE SOUTHWEST LATE TONIGHT
AND INCREASE TO A POINT WHERE WINDS AND WAVES MAY AGAIN BE A
THREAT TO SMALL CRAFT...BUT THIS SHOULD OCCUR AFTER MIDNIGHT WITH
WINDS AND WAVES REMAINING A POTENTIAL THREAT THROUGH THE DAY ON
THURSDAY.
